N48 Neodymium Magnet
N48 is a high-performance neodymium iron boron (NdFeB) magnet grade that provides strong magnetic output under standard operating temperature conditions. It is commonly selected when higher magnetic strength is required without the need for elevated temperature resistance.
Performance Characteristics
High Remanence (Br):
Delivers strong magnetic flux density, enabling compact and efficient magnetic designs.
- High Energy Product (BHmax):
Supports high power density and improved performance in limited installation space.
- Standard Temperature Rating:
Designed for stable operation up to 80°C, suitable for most normal working environments.
- Good Manufacturability:
Widely available and consistent in production, making it suitable for both mass production and engineered applications.
♦ Summary
N48 offers an excellent balance between strong magnetic performance and practical usability under normal temperature conditions. It is an effective choice for applications that prioritize high magnetic strength and space efficiency without exposure to high heat
Appearance & Dimensional Inspection
Visual inspection is conducted to verify surface condition, including:
- Coating uniformity and coverage
- Absence of cracks, chips, or surface defects
- Dimensional inspection ensures compliance with design specifications and tolerances.
Precision measuring tools such as digital calipers, micrometers, and gauges are used to measure:
Length, width, thickness, diameter, and critical features
Special attention is given to functional dimensions, including holes, chamfers, and countersunk structures.
Inspection results are recorded to ensure traceability and batch consistency.

FAQ
Q: What is the purpose of the slot or hole in the magnet?
The slot is designed for precise mechanical alignment, fastener placement, or structural integration in assemblies such as motors, fixtures, or magnetic couplings.
Q: Is demagnetization a concern during transport or long-term use?
No, unless exposed to strong reverse fields or extreme heat. Proper storage and magnetization protection ensure long-lasting performance.
Q: How long does salt spray testing last for this magnet?
Our coatings pass neutral salt spray tests up to 96h, 240h, or even 720h depending on the coating type. Test reports are available on request.
